SizeGenetics™ is a certified medical device product with safety and efficacy assessed under Medical Device Directive 93/42/EEC in Europe. Always read the product directions before use. As with other products, seek professional advice before using if you suffer from food allergies, and consult your doctor or pharmacist if you have an underlying medical condition (e.g. diabetes, epilepsy, hyperthyroidism), or if on medication. This site contains numerous testimonials, which are all examples of results achieved by real users. Testimonials may be edited for clarity and in some cases actors have been used to read written testimonials submitted by our customers or stock photography. Results may vary. The SizeGenetics™ device does not guarantee permanent penis enlargement. Claims for top selling device and number of years the device has been available on the market are based on Permenda sales and that of our Manufacturer. “Most powerful” claims are based on the device tension of 2800 grams and the fact that after a review of the market there are no other clinically proven devices with this tension. Comfort claims are based on the fact, that after performing a review on the market it is clear there is no device with the flexibility of SizeGenetics™.
